Mods: posting the older article because WTRF has not updated their site with the information the deputy is now out of the hospital. IIRC what I heard on a recent newscast of theirs, the injured deputy will be off duty for a month as a result of this accident.

Questions to the banglist: any ideas what might cause the Glock 21 to fly apart like this? AFAIK, the Marshall County (WV) SD has sent the pistol and ammo in question back to Glock for analysis.

+P+ ammunition? Uncleared barrel obstruction?

Without seeing the remains of the weapon its hard to say.

[SWAMPSNIPER]

I heard there were some slide failures.

“with out of country ammunition”

Why are our police and sheriff’s buying ammo made outside the USA?

Squib load followed by a live round...

[AnAmericanMother]

My guess, if he was using cheap reloads, is that somebody at the factory double-charged the shell. With a .45 ACP, that would be enough to shatter the case and the receiver as well.

I'm not as familiar with the Glock as the 1911A1 and the Sig, but whatever the weak point of the receiver is (locking lugs, ejector mount) would blow first, and if that's in the rear of the receiver you take the brunt of it on your hand and face (hopefully he had good shooting glasses).

Maybe a squib??

[TheThirdRuffian]

I am personally suprised a GLOCK would do that, barring barrel obstruction.

I have several .40s, and they are seriously stout weapons.

Curious if the .45 is a “hollowed out” .40 or somesuch, making thinner walled (and thus weaker) by design.

Double charge.

[DesertRhino]

Don’t think you are supposed to shoot unjacketed lead rounds in those due to the rifling technique used. Cheap reloads with lead foul the barrel to the point this can happen.

Loading error -— double powder charge ...

[Xenalyte]

Yikes ping!

[saganite]

Bullet stuck in the barrel from a squib load and subsequent failure when the deputy fired the next round. You said he was using questionable ammo so it’s possible. With a squib load the gun doesn’t go bang like it would normally and the slide won’t feed the next round so you’ve got 2 warning signs that something is wrong. I have had a squib load in my .45 (I reload so the fault was all mine) but I knew to check the barrel for an obstruction. Of course, it may not have been a squib load but it’s one possibility.

[PGalt]

Interesting post and thread. Thanks to all contributors.

What is the root cause? How many time has that ever happened? What is the probability of that happening? What variables need to be addressed?

[Deaf Smith]

There is a difference between 45ACP & 45AGP.

[muddler]

IIRC from the first story that I read on one of the gun boards, Was that it was the first round fired from a brand new Glock....

[Durus]

I'm not a glock hater but if you do “bing” (I'm not using google anymore) on “glock kaboom” you will come up with quite a few hits.

The rifling in glock’s pistol barrels are what is commonly referred to “polygonal” type and while there are advantages in both manufacturing and application they do foul with lead easier. When fouled they can actually cause a kaboom.

[Stray Gator]

No doubt he was using Wolf ammo from russia. I used it once and had lots of trouble with 45 acp. 9mm no problem. Its cheap but not worth it.

[old3030]

The feed ramp on a .40 Glock is oversized so the case is not fully supported. Because the .40 S&W is a high pressure round, brass weakened by repeated reloading will sometimes result in a catastrophic head separation. That shouldn't happen with the lower pressure .45 ACP, but I'm not familiar with the .45 GAP -- if that was the caliber.

I shoot a Springfield XDM myself.

[Tallguy]

Glock tells you to use only fully jacketed ammo and absolutely no re-loads. There is also a problem with the cartridge being unsupported on the .40SW Glocks due to the geometry of the infeed ramp. Might be a similar thing with the .45ACP, but I don’t know.

Google ‘Glock KaBoom’ and you’ll get all the dope.
